The Hornady DGX Bonded (Dangerous Game eXpanding) bullets features a copper-clad steel jacket bonded to a lead core to provide limited, controlled expansion with deep penetration and high weight retention. Bonding the jacket to the core prevents separation from high-energy impact on tough material like bone, ensuring the bullet stays together for deep expansion. DGX Bonded bullets are built to the same profile as the corresponding DGS (Dangerous Game Solid) bullets but expand to 1A 1/2 to 2 times their bullet diameter. This is not loaded ammunition.
